If piping is going through the right or left side:
1.Use a small saw blade to carefully remove the correspond- ing plastic covering on side panel and drill the appropriate size hole where the pipe is going through the wall. See Fig. 8(c).
2.Remove knockout 1 if you are running only the wiring. Remove knockout 1 and 2 or knockout 1, 2 and 3 if you are running both piping and wiring through the side of the unit.
OUTDOOR UNIT INSTALLATION
1.Use a rigid base to support unit in a level position.
2.Locate outdoor unit and connect piping and wiring.
!CAUTION
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or improper operation.
Excessive torque can break flare nut depending on installation conditions.
Piping Connections to Outdoor Unit
IMPORTANT: Use refrigeration grade tubing ONLY. No other type of tubing may be used. Use of other types of tubing will void manufacturer’s warranty.
Make sure there is enough piping to cover the required length between the outdoor and indoor unit.
Piping Guide:
SDo not open service valves or remove protective caps from
tubing ends until all the connections are made.
SBend tubing with bending tools to avoid kinks and flat spots. S Keep the tubing free of dirt, sand, moisture, and other
contaminants to avoid damaging the refrigerant system.
S Avoid sags in the suction line to prevent the formation of oil traps. Insulate each tube with minimum
1.Remove service valve cover if provided with unit.
2.Cut tubing with tubing cutter.
3.Install correct size flare nut onto tubing and make flare con- nection.
4.Apply a small amount of refrigerant oil to the flare connec- tion on the tubing.
5.Properly align tubing in with service valve.
6.Tighten flare nut and finish installation using two wrenches as shown in Fig. 10.

!CAUTION
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or improper operation.
SBe sure to comply with local codes while running wire
from indoor unit to outdoor unit.
SEvery wire must be connected firmly. Loose wiring may cause terminal to overheat or result in unit malfunction.
A fire hazard may also exist. Therefore, be sure all wiring is tightly connected.
SNo wire should be allowed to touch refrigerant tubing, compressor or any moving parts.
SDisconnecting means must be provided and shall be
located within sight and readily accessible from the air conditioner.
SConnecting cable with conduit shall be routed through hole in the conduit panel.
